CVE-2024-8285Network attack vector

Kafka traffic interception via unchecked TLS hostname

Published Aug 30, 2024 · Updated Nov 20, 2025

Improper TLS hostname validation in Kroxylicious before 0.8.0 allows man-in-the-middle attackers to intercept upstream Kafka traffic. The upstream connection setup accepts a trusted certificate without checking that its identity matches the configured Kafka broker hostname. An attacker must control a network path, DNS, routing, a peer system, or proxy configuration; successful interception exposes and permits modification of proxied data.
